Blockchain technology took the world by storm a couple of years ago and the market for blockchain-related products have grown to more than a trillion dollars. Some people consider the market as pure speculation on nothingness while others consider the market as an opportunity in terms of investment or solving real world problems. Nevertheless, to navigate this space, one needs to acquire a minimal understanding of the market and the various entry points. In this series of blogpost on Crypto Guide, I will be explaining from a user perspective the steps that I have learnt and used to navigate the blockchain technology space. After this guide, I am sure that navigating the space is not as daunting as it may first appear to be, and a whole new world and community will be revealed to you.
[Part 1] Purchasing My First Cryptocurrency: Creating a Wallet
Before you can purchase your first cryptocurrency, there are several things you have to do. First, you need a wallet to store your cryptocurrency and to make transactions. This step is optional if you just intend to trade cryptocurrency in an exchange. However, if you wish to explore the world of blockchain technology, it is imperative that you acquire a wallet.
There are two kinds of wallet: a hot wallet and a cold wallet. A hot wallet is a digital wallet that stores your crypto on the internet. A cold wallet is a physical wallet that you store outside of the internet. There are pros and cons to having a cold or a hot wallet. Personally, I trust the security of the exchanges and wallets that I use, thus I am comfortable with just using a hot wallet.
Cold Wallet
1. Less prone to hacking as the crypto is stored offline.
2. Not always supports the different blockchains.
3. If you lose the physical wallet, you lose the crypto. If you lose your keys to your physical wallet, you lose the crypto.
Hot Wallet
2. More prone to hacking.
2. Able to download various kinds of wallets that support different kinds of blockchains.
3. You only lose the crypto if you lose your keys.
Thus, the most defining aspect between the two is the security of your crypto. Another thing that I should clarify are the keys. Keys allow you to access your crypto from several different devices or even salvage a crypto wallet when you accidentally delete the wallet in your device. A key can be in the form of a password, OTP verification, thumbprint verification, or a seed phrase and this varies from wallet to wallet.

The most important key for any wallet is the Seed Phrase. When you create a new wallet, hot or cold, you are given a Seed Phrase which is usually a 24 word list. Write this important Seed Phrase in two notebooks and store it somewhere safe. Do not store and type the Seed Phrase in your computer because someone can hack and steal it. Giving someone this Seed Phrase is essentially giving that person your entire wallet. There is an important saying in the crypto space which is: "Not your keys, not your crypto." I have been around in several Discord chats and people have lost their Seed Phrases and essentially their entire crypto savings when they lose their seed phrase.
Seed Phrases are also useful if you intend to use several device to access you crypto wallet. After installing the wallet in a new device, the wallet app or extension will prompt you to enter your Seed Phrase. Thus, you can simply enter your 24 words and your crypto wallet will be made available to you.
The great thing about seed phrases and the security of wallets is that someone stealing your device with your crypto wallet already installed in it do not immediately have access to your crypto wallet. For hot wallets, your crypto is stored on the blockchain itself which cannot be physically stolen. The person will either need to steal your password to the hot wallet or steal your Seed Phrase. Thus, the important number one rule: Not your keys, not your crypto.
Which Wallet Should I Use?
From here on forth, I will be speaking solely on experience. I chose to only use a hot wallet due to the efficiency of hot wallets and my belief in the security of the wallet and exchanges that I use. There are several different kinds of hot wallets in the market. It is free for you to install these wallets and usually, hot wallets simply charge a percentage fee for making transactions using their wallets.
The type of hot wallet that you need depends on the cryptocurrency that you intend to purchase or make transactions with. You have to think of blockchain technology as a network, like the internet. There is Ethereum and Bitcoin, the current two most popular cryptocurrency. They operate on two different networks. That means that if you have a wallet that supports the Ethereum network only, you would not be able to store and transact Bitcoins in that wallet.
Thankfully blockchain technology and wallet creators have developed features which allows you to transfer cryptocurrencies between blockchains. For example, you may find an application that was developed on the Ethereum network that accepts Bitcoin payment. How? Bitcoin can be wrapped in an Ethereum-compatible layer and transacted using a side chain on the Ethereum network. There are different strategies that wallet and apps use to enable cross-functionality between different blockchains, but the important thing to note is that it is possible.

The most useful and widely used wallet that you most definitely must have is a Metamask wallet. You will find that almost all applications and exchanges accepts this wallet and may even be a requirement to use a lot of dapps. If this is your first time, you need to sign up for a metamask wallet account in the Metamask website, metamask.io, and follow the steps to set up an account. A Seed Phrase will be given to you, and this is the part where you write it down in a notebook.
If you are using a computer, you must get a metamask extension and bookmark it. I use Chrome and the extension will appear on the top right hand corner of the browser after you have bookmarked it. If you need to access it, you can simply click on the Metamask icon which is a picture of a fox, and enter your password. If you are using a phone, you have to download the metamask app. Making purchases or transactions through your phone is a little inconvenient as you may need to use the metamask app as a browser and this is not the most user-friendly.
There are also several other different wallets that are available but I would recommend you to only install the wallet that you need to use because the most common cryptocurrencies can already be transacted using your Metamask wallet. However, if there is an altcoin that is not supported by Metamask and/ or have its own wallet that carries more benefits for their users, then do go ahead and use it. One example is the Binance wallet that facilitate transactions on the Binance network. It is possible for you to create a Binance node in you Metamask wallet to support Binance transactions, however, if you are unfamiliar as to how to install a node, you can simply use the Binance wallet. Unfortunately, not all apps support the Binance wallet. For example, a popular blockchain game, mydefipet only allows players who have a metamask wallet with Binance nodes installed to play and does not support the Binance wallet. (Another example why Metamask is the most important wallet to have.)
In Singapore, there are currently no restrictions to downloading and installing hot or cold wallets such as Metamask or Ledger. Downloading Metamask is also free. Metamask only charges a very minimal sum which is almost negligible when you make transactions using their wallet.
Now that you know how to create a wallet, the next step is to create an account in a crypto exchange to buy some crypto. Do check out Crypto Guide Part 2 to find out how!
